nIFTy Galaxy Cluster simulations VI: The dynamical imprint of substructure on gaseous cluster outskirts
C. Power, P. J. Elahi, C. Welker +11
Galaxy cluster outskirts mark the transition region from the mildly non-linear cosmic web to the highly non-linear, virialised, cluster interior. It is in this transition region th…
Observing Merger Trees in a New Light
Rhys J. J. Poulton, Aaron S. G. Robotham, Chris Power +1
Merger trees harvested from cosmological -body simulations encode the assembly histories of dark matter halos over cosmic time, and are a fundamental component of semi-analytica…
The Three Hundred project: a large catalogue of theoretically modelled galaxy clusters for cosmological and astrophysical applications
Weiguang Cui, Alexander Knebe, Gustavo Yepes +34
We introduce the THE THREE HUNDRED project, an endeavour to model 324 large galaxy clusters with full-physics hydrodynamical re-simulations. Here we present the data set and study…
Cosmic Voids in Evolving Dark Sector Cosmologies: the High Redshift Universe
Eromanga Adermann, Pascal J Elahi, Geraint F Lewis +1
We compare the evolution of voids formed under the standard cosmological model and two alternative cosmological models. The two models are a quintessence model (CDM) and a Coupl…
Shark: introducing an open source, free and flexible semi-analytic model of galaxy formation
Claudia del P. Lagos, Rodrigo J. Tobar, Aaron S. G. Robotham +4
We present a new, open source, free semi-analytic model (SAM) of galaxy formation, Shark, designed to be highly flexible and modular, allowing easy exploration of different physica…
Introducing a new, robust galaxy finder algorithm for simulations
Rodrigo Cañas, Pascal J. Elahi, Charlotte Welker +4
Identifying galaxies in hydrodynamical simulations is a difficult task, particularly in regions of high density such as galaxy groups and clusters. We present a new scale-free shap…
